LOLOL. I sure am glad I hadn't heard of the Dixie Rangers...especially since I live in the South! Sadly, I haven't heard of Dixie Rainbows either! I'm just not well-informed, I guess. I guess this has been a very unfortunate lesson. I don't know what the overall consensus is about Mt...
Gosh, that is horrible. I am not familiar with the Dixie Rangers, but I assume that it is some kind of hybrid. Sounds like it is a bad breed or a bad hatch. If it were something contagious, you RIR's would be sick if they're in the same brooder.
I think that I would stay away from that...
